Product Usage Instructions
- Before flying, perform pre-flight checks:
- Check and adjust servo centering for better control surface
adjustment. - Double-check the spinning direction of the motor to ensure it
is suitable for your model. - Set the center of gravity (CG) at the position marked in the
manual. Add weight to the nose or tail if necessary for optimal
flight performance. - Check the inside of the fuselage to ensure all equipment is
correctly connected. Verify the surface of the heat-shrink covering
material and ensure all screws, bolts, cabin, and canopy are
secure. - Take care when connecting/disconnecting the battery. Replace
the battery immediately if low voltage or damage is detected. - Review the connection of internal devices in relation to your
transmitter-receiver device. Simplify the connection if your device
supports it. Refer to your device’s instructions for details. - When pairing the power system and transmitter-receiver device
for the first time, set the maximum throttle stroke as
required.
- This product is not a toy and should be operated by individuals
who understand its complexity. Your safety and the safety of others
depend on correct usage. - Do not fly in restricted locations such as airports, military
bases, or residential areas. - Perform a range check on the transmitter to ensure no
interference is experienced. - Turn on the transmitter before turning on the receiver, and
turn off the receiver before turning off the transmitter. - If you are a beginner, seek assistance or advice from advanced
expert fliers before flying the model. - Keep relevant items out of reach of children.
- If engaging in high-stress flying, take necessary steps to
control movement range and reinforce the body strength. You are
solely responsible for this. - Some parts of this product may cause discomfort to the eyes and
skin. Wear goggles or dust-proof clothes when needed. - The glue mentioned in the list may not be included due to air
traffic safety control. Purchase the required glue from a local
stationery store.

PRE-FLIGHT CHECKS
Check/adjust servo centering, in order to adjust the control surface better.
Double-check the spinning direction of motor at first usage, and sure it’s suitable for your model.
CG Set the center of gravity (CG) at the position that manual already marked out. If necessary, add weight to the nose or tail to ensure the best flight performance.
Double-check the inside of the fuselage, make sure all the equipments are correctly connected; Check the heat-shrink covering material’s surface, Make certain all screws, bolts, cabin and canopy remain secure.
Take great care when connecting/disconnecting the battery, pls replace the battery immediately once found low voltage or damage to battery.
The way the internal devices of the fuselage are connected will be related to your transmitter-receiver device. For those transmitter-receiver devices with more functions, you can simplify the connection of the internal devices of the fuselage. Check your device for details to see if it meets the features you need.
When the power system and transmitter-receiver device are paired for the first time, you may need to set the maximum stroke of the throttle. Please set it yourself.
SAFETY PRECAUTIONS
14 This product should not be considered a toy, but rather a complicated and sophisticated flying model. Your safety depends on how you use and fly it, If not correctly operated, could cause injury to you or your family members.
